What Cometic HG should I buy?

[SupraJDS]

I am about to buy my Cometic HG from http://www.horsepowerfreaks.com/price/Toyota/Supra_86-92/Cometic/Engine/Head_Gaskets - I looked at each description but still don't know which one to get. My head and block have never been Machined or laped, but are Basically perfect. So which one would be the best to buy?

Thanks guys,
Josh

Edit:What is the stock thickness, I searched but alot of different opinions came up.

if ur not going to lap the head and block. dont buy a MHG. its not worth it. ull be doing ur hg again sooner then u think. basically perfect doesnt cut it

not true just check for warpage with a strait edge and feeler gauges you can do it yourself just make sure its in spec... the block will probably be perfectly fine the head may be a little off.. no matter what it will definately be worth putting a nicer HG in and proper tourque with ARP's you will be fine, i have ran the 1.2mm HKS and the 1.4mm titan currently both have never even thought about giving me problems rabid chimp sells them for about 140$ shipped either one

That should answer you're question about the differences.

do what u want, but i wouldnt spend a bunch of money and go through the trouble of putting in a mhg without doing the prep work first. if i was going to just take the head off and replace the HG. i would at LEAST shave the head and put in a compostie headgasket. but to each his own.
